Information Retrieval in Biomedicine: Natural Language Processing for Knowledge Integration

Currently, the most successful general purpose retrieval methods are statistical methods that treat text as little more than a bag of words. However, attempts to improve retrieval performance through more sophisticated linguistic processing have been largely unsuccessful.

Indeed, unless done carefully, such processing can degrade retrieval effectiveness. Several factors contribute to the dificulty of improving on a good statistical baseline including: the forgiving nature but broad coverage of the typical retrieval task; the lack of good weighting schemes for compound index terms; and the implicit linguistic processing inherent in the statistical methods.

Natural language processing techniques may be more important for related tasks such as question answering or document summarization. Unable to display preview. Download preview PDF. Skip to main content. This service is more advanced with JavaScript available. Advertisement Hide.

Natural language processing and information retrieval methods for intellectual property analysis. More intellectual property information is generated now than ever before. The accumulation of intellectual property data, further complicated by this continued increase in production, makes it imperative to develop better methods for archiving and more importantly for accessing this information. Information retrieval IR is a standard technique used for efficiently accessing information in such large collections.

NLP - Information Retrieval

Violaine Prince, Mathieu Roche, editors. For a number of years, librarians have heard that natural language processing NLP will revolutionize information management and retrieval in health care settings. The goal of the two editors, professors at the University Montpellier 2 in France, is to compile research that librarians and health information systems administrators and developers will find useful in incorporating data management systems solutions into their organizations. This book provides relevant theoretical frameworks and empirical research findings in NLP according to linguistic granularity and presents original applications. Both editors demonstrate expertise in the field of computer science.

Information retrieval IR may be defined as a software program that deals with the organization, storage, retrieval and evaluation of information from document repositories particularly textual information. The system assists users in finding the information they require but it does not explicitly return the answers of the questions. It informs the existence and location of documents that might consist of the required information. A perfect IR system will retrieve only relevant documents. It is clear from the above diagram that a user who needs information will have to formulate a request in the form of query in natural language.

Although the management of information assets—specifically, of text documents that make up 80 percent of these assets— an provide organizations with a competitive advantage, the ability of information retrieval IR systems to deliver relevant information to users is severely hampered by the difficulty of disambiguating natural language. The word ambiguity problem is addressed with moderate success in restricted settings, but continues to be the main challenge for general settings, characterized by large, heterogeneous document collections.

Information retrieval IR involves retrieving information from stored data, through user queries or pre-formulated user profiles. The information can be in any format. IR typically advances over four broad stages viz.
