biopharmaceutical informatics: Drug companies go through a very arduous and regulated discovery, applied research, and development process- typically spanning five years of laboratory research and ten years of clinical studies .. multinational clinical studies, which need to be done with tremendous precision over a very long period of time. The study parameters must be identical for every patient (many times numbering 10,000 patients, followed for five or more years), and all the participating hospitals essentially have to behave in exactly the same way for the trial to be valid. ..  The life science industry is conservative by nature, and therefore it is a late- adopting industry. It is very sensitive to standards because of the legacy according to which these companies have to maintain data and information. Major pharmaceutical companies typically adopt a 100-year minimum document retention policy, ...each of the industry's four industrial sectors - the pharmaceutical, the biotech, the medical device, and the diagnostics sector - has a different set of needs and desires, as well as its own requirements for unique IT solutions.  ... 

Life science companies are dealing with very large computational data sets. Some are now approaching half terabyte sizes and upward Life science companies also immensely concern themselves with security, because their data represent their crown jewels. Other major concerns expressed by this industry include the stability, scalability, and security of an operating environment. Life science companies and regulatory bodies such as the FDA are more concerned than ever with operating environments that decay with use: When under computational stress, these fragile operating systems have a habit of crashing, and when these systems crash, they tend to corrupt data. ...

Post-genomic, proteomic, chemical information, and other data sets have created a major appetite for solutions to deal with this tremendous amount of data. Scientists are now asking their IT professionals for the ability to better conceptualize and interpret the meaning of this vast information. To do this, scientists need tools for 3D visualization with a tremendous degree of high definition and accuracy. The next step is to take disparate data sets, render them into 3D values, see the DNA and RNA interface, watch protein folds, and then put a therapeutic small molecule in there and see how it relates within a virus that environmentally influences a different process.

blogging:  In the beginning - say 1994 - the phenomenon now called blogging was little more than the sometimes nutty, sometimes inspired writing of online diaries. These days, there are tech blogs and sex blogs and drug blogs and onanistic teenage blogs. But there are also news blogs and commentary blogs, sites packed with links and quips and ideas and arguments that only months ago were the near- monopoly of established news outlets. Poised between media, blogs can be as nuanced and well- sourced as traditional journalism, but they have the immediacy of talk radio.  Andrew Sullivan, "The blogging revolution" Wired Magazine, May 2002 http://www.wired.com/wired/archive/10.05/mustread.html?pg=2

classification: Involves the development and use of a scheme for the systematic organization of knowledge. (Taylor p 576) Arlene Taylor identified three approaches to classification: enumerative, hierarchical, and analytico- synthetic. Enumerative classification attempts to assign headings for every subject and alphabetically enumerates them. Hierarchical classification uses a more philosophical approach based on the inherent organization of the subject being classified, and establishes logical rules for dividing topics into classes, divisions, and subdivisions. Analytico- synthetic classification assigns terms to individual concepts and provides rules for the local cataloger to use in constructing headings for composite subjects. Traditional classification systems in this country are basically enumerative, though many contain some elements of hierarchy and faceting. (Taylor pp 319- 321) Amanda Maple, "FACETED ACCESS: A REVIEW OF THE LITERATURE" Working Group on Faceted Access to Music, Music Library Association Annual Meeting, 10 February 1995 http://theme.music.indiana.edu/tech_s/mla/facacc.rev  

Indexing in the library and information management sense. See also classification, classifiers

classification: Can be done manually by human experts or automatically by software of many different types. However, the term as used in the microarray field has a more specific meaning: It always refers to automatic methods, and usually means automatic methods in which the classifier is built by adjusting parameters of a general model. These methods are sometimes called supervised computer- learning methods, in contrast to unsupervised methods, such as clustering. 

classifier:  A decision procedure that categorizes data into two or more predefined groups. Classifiers are also called predictors. Classifiers usually emit a score that can be interpreted as the likelihood that the data fall into a certain category, rather than just a binary yes/ no answer. In many applications it is necessary to convert this likelihood into a yes/ no answer, or perhaps a yes/ no/ maybe answer, typically through a simple thresholding scheme.

computational linguistics:  Computational Linguistics, or Natural Language Processing (NLP), is not a new field. As early as 1946, attempts have been undertaken to use computers to process natural language. These attempts concentrated mainly on Machine Translation ... the limited performance of these systems made it clear that the underlying theoretical difficulties of the task had been grossly underestimated, and in the following years and decades much effort was spent on basic research in formal linguistics. Today, a number of Machine Translation systems are available commercially although there still is no system that produces fully automatic high- quality translations (and probably there will not be for some time). Human intervention in the form of pre- and/ or post-editing is still required in all cases.  Another application that has become commercially viable in the last years is the analysis and synthesis of spoken language, i.e. speech understanding and speech generation. ... An application that will become at least as important as those already mentioned is the creation, administration, and presentation of texts by computer. Even reliable access to written texts is a major bottleneck in science and commerce. The amount of textual information is enormous (and growing incessantly), and the traditional, word- based, information retrieval methods are getting increasingly insufficient as either precision or recall is always low (i.e. you get either a large number of irrelevant documents together with the relevant ones, or else you fail to get a large number of the relevant ones in the collection). Linguistically based retrieval methods, taking into account the meaning of sentences as encoded in the syntactic structure of natural language, promise to be a way out of this quandary.

configurable: Many out-of-the-box solutions claim to be easy to "customize," when in fact they are referring to configuration options, not true customizability.  Manufacturers have distinct challenges, some which can be addressed out of the box, but many of which cannot. Manufacturers also need the ability to capitalize on changing dynamics in the marketplace before their competitors do. That's why it's imperative to understand the differences between configuration and customization and the value of selecting a CRM system that offers the flexibility to adapt and model specific manufacturing business processes.  Why you need to know the difference between Customizable and Configurable CRM, CDC Software podcast, Intelligent Enterprise,  2006  http://www.blogmanno.com/?q=node/33 

Customized implies programming and expense.  Configurable gives users the chance to modify options, without expensive programming. 

contextual data: While proteomic studies initially focused largely on expression and protein identification, progress in these areas drove the demand for more detailed types of proteomic data. Now researchers want information about where specific proteins are expressed, both in terms of tissues and localization within the cell. Information relating proteins to function require additional details of post- translational modification, and studies of protein interactions have moved beyond just looking at binary interactions to studies of protein complexes.

For both genomics and proteomics, this shift can be characterized as an interest in more contextual data. Enhanced insight into biological context is essential for obtaining a better understanding of how biology actually works, and thus there is now an emphasis to move from genomic and proteomic snapshots to time series data of expression. Such context is of particular value if biological studies are to be translated into medical advances, because of the importance of being able to predict the impact of potential treatments. The integration of genomic and proteomic data with medical conditions, treatment and outcomes becomes another critical type of contextual information.

A limited number of words or phrases used in an indexing system (subject headings) or database, to ensure reliable, consistent retrieval. Long used to enhance retrievability and consistency, ontologies and/ or taxonomies certainly sound sexier than "controlled vocabularies" but continue to have a good deal in common. Taxonomies add hierarchies, while ontologies make information "machine- understandable" as well as machine- readable.

granularity: Wikipedia http://en.wikipedia.org/wiki/Granularity 

<jargon, parallel> The size of the units of code under consideration in some context The term generally refers to the level of detail at which code is considered, e.g. "You can specify the granularity for this profiling tool". The most common computing use is in parallelism where "fine grain parallelism" means individual tasks are relatively small in terms of code size and execution time, "coarse grain" is the opposite. You talk about the "granularity" of the parallelism. The smaller the granularity, the greater the potential for parallelism and hence speed- up but the greater the overheads of synchronisation and communication. FOLDOC 1997  http://www.swif.uniba.it/lei/foldop/foldoc.cgi?granularity 

The extent to which a system contains separate components (like granules). The more components in a system - or the greater the granularity - the more flexible it is. [Webopedia] http://www.webopedia.com/TERM/g/granularity.html

Choosing different levels of granularity, i.e., imposing different quality criteria on models built by homology from representative, experimentally determined [protein] structures, leads to different numbers of family representatives as targets.

information management:  Information services of various kinds are fundamental to the discovery, development and use of medicines. Within the pharmaceutical industry, often regarded as the epitome of the 'information intensive' industry, research information units provide both external and internal information provision and management to discovery and development programmes, while medical information units provide in- depth information on the company's products to external doctors, pharmacists, etc., and commercial information units handle information on competitors, marketing data, etc. Additionally, information personnel are involved in activities such as records management and archiving, regulatory affairs, data administration, IT support, and many more. Within the NHS [National Health Service, UK] , Drug Information Pharmacists provide information services on effective use of medicines to all healthcare professions, and are also involved in databases compilation, records management, current awareness etc. The move towards evidence- based medicine, with consequent need for evaluation and presentation of information, is of obvious importance to this group.

Delays in the exploitation of the discoveries will be costly in terms of health benefits for individuals and will adversely affect the economic edge of the country. [Opportunities in Molecular Biomedicine in the Era of Teraflop Computing: March 3 & 4, 1999, Rockville, MD, NIH Resource for Macromolecular Modeling and Bioinformatics Beckman Institute for Advanced Science and Technology, University of Illinois at Urbana- Champaign] http://www.ks.uiuc.edu/Publications/Reports/teraflop/node4.html

Many of today's problems stem from information overload and there is a desperate need for innovative software that can wade through the morass of information and present visually what we know.  The development of such tools will depend critically on further interactions between the computer scientists and the biologists so that the tools address the right questions, but are designed in a flexible and computationally efficient manner.  It is my hope that we will see these solutions published in the biological or computational literature.  Richard J. Roberts, The early days of bioinformatics publishing, Bioinformatics 16 (1): 2-4, 2000

"Information overload" is not an overstatement these days. One of the biggest challenges is to deal with the tidal wave of data, filter out extraneous noise and poor quality data, and assimilate and integrate information on a previously unimagined scale

information visualization: The direct visualization of a representation of selected features or elements of complex multi- dimensional data. Data that can be used to create a visualization includes text, image data, sound, voice, video - and of course, all kinds of numerical data. Our visual analysis systems also provide the tools to interact with the data that has been visualized so that users can explore, discover and learn. Users do not look at static images, but can subset the data, run queries, do time sequence studies and create categories and correlations of data type.

life sciences informatics: Informatics are essential at every step of genomics- based drug discovery and development. The commercial landscape of life sciences information technology has changed dramatically in the last few years. Bioinformatics, in particular, has gone through a dramatic boom/bust. While IT companies are looking to the drug discovery and development arena as a new market opportunity, pharmaceutical companies  are faced with rising pressure to reduce (or at least control) costs, and have a growing need for new informatics tools to help manage the influx of data from genomics, and turn that data into tomorrow's drugs. Key IT tools, such as high- performance computing, Web services, and grids, are being used to improve the speed and efficiency of drug discovery and development. True breakthroughs are still lacking, particularly in key areas such as gene prediction, data mining, protein structure modeling and prediction, and modeling of complex biological systems. However, most experts agree that IT and bioinformatics are essential to reaching the improved productivity the pharmaceutical industry craves.

Medical informatics has to do with all aspects of understanding and promoting the effective organization, analysis, management, and use of information in health care. While the field of medical informatics shares the general scope of these interests with some other health care specialties and disciplines, medical informatics has developed its own areas of emphasis and approaches that have set it apart from other disciplines and specialties. For one, a common thread through medical informatics has been the emphasis on technology as an integral tool to help organize, analyze, manage, and use information. In addition, as professionals involved at the intersection of information and technology and health care, those in medical informatics have historically tended to be engaged in the research, development, and evaluation side of things, and in studying and teaching the theoretical and methodological underpinnings of data applications in health care. However, today medical informatics also counts among its profession many whose activities are focused on dimensions that include the administration and everyday collection and use of information in health care.

metadata: Could elevate the status of the web from machine- readable to something we might call machine- understandable. Metadata is "data about data" or specifically in our current context "data describing web resources." The distinction between "data" and "metadata" is not an absolute one; it is a distinction created primarily by a particular application ("one application's metadata is another application's data"). [W3C, "Introduction to RDF Metadata" 1997] http://www.w3.org/TR/NOTE-rdf-simple-intro

Metadata is machine understandable information for the web.

ontology, ontologies:  The word "ontology" seems to generate a lot of controversy in discussions about AI  [artificial intelligence]. It has a long history in philosophy, in which it refers to the subject of existence. ... In the context of knowledge sharing, I use the term ontology to mean a specification of a conceptualization. That is, an ontology is a description (like a formal specification of a program) of the concepts and relationships that can exist for an agent or a community of agents. This definition is consistent with the usage of ontology as set- of- concept- definitions, but more general. And it is certainly a different sense of the word than its use in philosophy. What is important is what an ontology is for. My colleagues and I have been designing ontologies for the purpose of enabling knowledge sharing and reuse. In that context, an ontology is a specification used for making ontological commitments. ... Notes: 1) Ontologies are often equated with taxonomic hierarchies of classes, but class definitions, and the subsumption relation, but ontologies need not be limited to these forms.

social informatics:  Social Informatics (SI) refers to the body of research and study that examines social aspects of computerization, including the roles of information technology in social and organizational change, the uses of information technologies in social contexts, and the ways that the social organization of information technologies is influenced by social forces and social practices.  http://rkcsi.indiana.edu/ 

The term "Social Informatics" emerged from a series of lively conversations in February and March 1996 among scholars with an interest in advancing critical scholarship about the social aspects of computerization, including Phil Agre, Jacques Berleur, Brenda Dervin, Andrew Dillon, Rob Kling, Mark Poster, Karen Ruhleder, Ben Shneiderman, Leigh Star and Barry Wellman. As the conversation developed, it became clear that labels that could energize scholars in one sub- community could readily turn off participants in other communities. Various participants preferred different labels; a sufficient consensus emerged around "Social Informatics" that it can serve as a working label.  ["Conceptions of social informatics" Indiana Univ., School of Library and Information Science, 2002] http://www.slis.indiana.edu/SI/concepts.html

A serviceable working conception of "social informatics" is that it identifies a body of research that examines the social aspects of computerization. A more formal definition is "the interdisciplinary study of the design, uses and consequences of information technologies that takes into account their interaction with institutional and cultural contexts." ... Social informatics has been a subject of systematic analytical and critical research for the last 25 years. Unfortunately, social informatics studies are scattered in the journals of several different fields, including computer science, information systems, information science and some social sciences. Each of these fields uses somewhat different nomenclature. This diversity of communication outlets and specialized terminologies makes it hard for many non- specialists (and even specialists) to locate important studies.

structure:  In a biological or anatomical context, the term structure is associated with two distinct concepts (meanings): 1. a material object generated as a result of coordinated gene expression, which necessarily consists of parts (e.g., hemoglobin molecule, cell, heart, human body); and 2. the manner of organization or interrelation of the parts that constitute a structure specified by the first definition (i.e., the structure of a structure). Both definitions emphasize the critical need for declaring the principles according to which units of organization can be defined in order to be able to state what is 'whole' and what is 'part'. Specifying the manner in which parts interrelate must satisfy two requirements: 1. to determine the kinds of parts of which various structures may be constituted; and 2. to state the manner of spatial organization of parts by describing their boundaries, continuities and attachments, as well as their location, orientation and spatial adjacencies in terms of qualitative coordinates (in addition to the quantitative geometric coordinates, which are embedded in the Visible Human data sets).

text mining:  Usually data mining technologies mine knowledge from data with well-formed schemes such as relational tables. But, text data don't have such scheme, and information is described freely in the documents. Therefore, we focus on Natural Language Processing (NLP) technologies to extract such information. Using NLP technologies, documents are transformed into a collection of concepts, described using terms discovered in the text.

Usually, "text mining" is used to indicate a text search technique. But, we think of text mining as having more functions. Text mining technologies extract more information than just picking up keywords from texts: facts, author's intentions, their expectations, and their claims.  Tokyo Research Lab, IBM, Text Mining  http://www.trl.ibm.com/projects/textmining/index_e.htm

visualization:   A method of computing by which the enormous bandwidth and processing power of the human visual (eye- brain) system becomes an integral part of extracting knowledge from complex data.  It utilizes graphics and imaging techniques as well as knowledge of both data management and the human visual system.  [Lloyd Trenish, Visualization for Deep Thunder, IBM Research, 2002] http://www.research.ibm.com/weather/vis/w_vis.htm

Narrower terms: data visualization, information visualization; Algorithms & data analysis  dendogram, heat map, profile chart

visualisation: As the quantity of data produced by simulations grows, so does the difficulty of extracting useful information. It is now clear that in many applications visual methods are the only practical way of extracting information from the data. Computer graphics and scientific visualisation techniques have become more important in the last few years with the increased availability of computing resource and of visualisation tools.  Visualisation is becoming one of the key tools for problem solving both in traditional areas such as visualisation of complex flow and in new applications areas like the planning of surgical operations using 3-D recontruction of anatomical sites using diagnostic images or the development of highly-realistic aeroplane simulators for pilot training.  DIRECT Development of an Interdisciplinary Roundtable for Emerging Computer Technologies,  Edinburgh University, Scotland  http://www.epcc.ed.ac.uk/DIRECT/vect.html

web: The genome community was an early adopter of the Web, finding in it a way to publish its vast accumulation of data, and to express the rich interconnectedness of biological information. The Web is the home of primary data, of genome maps, of expression data, of DNA and protein sequences, of X-ray crystallographic structures, and of the genome project's huge outpouring of publications. ... However the Web is much more than a static repository of information. The Web is increasingly being used as a front end for sophisticated analytic software. Sequence similarity search engines, protein structural motif finders, exon identifiers, and even mapping programs have all been integrated into the Web. Java applets are adding rapidly to Web browsers' capabilities, enabling pages to be far more interactive than the original click- fetch- click interface. [Lincoln D. Stein "Introduction to Human Genome Computing via the World Wide Web", Cold Spring Harbor Lab, 1998]

web harvesting: A Web site is usually viewed as a collection of individual pages interconnected by a simple URL links. This is the common basis for Web harvesting engines, where these pages are harvested, indexed, and the search results made available to end- users. As Web sites become increasingly large and sophisticated, it is worthwhile to see how prevalent simple linking is, or if other Web page navigation techniques are replacing the simple linking model.

web service interoperability: Web services technology has the promise to provide a new level of interoperability between software applications.

Tim Berners- Lee writes in his account of coming up with the idea of the web Weaving the Web about "learning to think in a weblike way". I don't know that I can claim to approach this yet, but the more that I write and research this glossary on and for the web, the more insight I'm getting into what he might mean. Metaphors like "shooting at a moving target" and like Wayne Gretzky "skating to where the puck is going to be" are helpful images.

Wiki collaborative software: Allows users to post and edit content remotely. An exciting (and free) way to build and manage content. Wiki Web sites  allow all users to add and edit content. While it might sound like a free-for-all, the authors suggest such Web sites have been used successfully in research, business, and education to document project designs, for brainstorming, and for otherwise creating content in a collaborative fashion.  Bo Leuf, Ward Cunningham, The Wiki Way: Collaboration and sharing on the internet,  2001
