- Abstract
- Contribution to the ongoing debate on the French subject headings list RAMEAU, which has been much criticised as time consuming and inflexible. Proposed technical solutions to recurring problems with complex syntax, strucutre of hierarchical and associative links, and rigity of language are discussed, in the context of computerised cataloguing and retrieval using OPACs. As a universal indexing language RAMEAU is more appropriate for medium sized specialised libraries and specialist researchers. However the 2 possible subject indexing techniques, linguistic treatment of whole text and thesaurus, are now beginning to be viewed as complementary approaches

- Abstract
- The encyclopedic indexing system RAMEAU is used in bibliographic records derived from BN-OPALE and Electre, the chief sources in France, and hence by an increasing number of libraries. Because it is designed to cover all subjects for all types of users, RAMEAU is complex, with numerous strict rules. This has led to criticism but if used systematically with appropriate software, it produces a high retrieval rate. The central principle is the distinction between authorities and subject headings, making it essential to create links between the two by including rejected and related terms. This is time consuming and produces better results than systems based on, for example, linguistic analysis

- Abstract
- For users, the catalogue is a tool to assist in satisfying information demands. Bibliographic databases raise the question of how to describe a document to facilitate retrieval. Information technology development have led to the creation of hypercatalogues, affording links to related material and other services. This necessitates improved descriptive cataloguing and also improved search interfaces to simplify user manipulation, along the lines of the Web. Given the massive output of electronic documents, the librarian's role is to select, prioritise and organise. The information society and its consequent economic consequences for the social organisation of knowledge raise the prospect of marginalisation of libraries. Catalogues enable access to knowledge as a public good, but this access must be democratic

- Abstract
- Discusses the apparently unattainable goal of compatibility of information languages. While controlled languages can improve retrieval performance within a single system, they make cooperation across different systems more difficult. The Internet and downloading accentuate this adverse outcome and the acceleration of data exchange aggravates the problem of compatibility. Defines this familiar concept and demonstrates that coherence is just as necessary as it was for indexing languages, the proliferation of which has created confusion in grouped data banks. Describes 2 types of potential solutions, similar to those applied to automatic translation of natural languages: - harmonizing the information languages themselves, both difficult and expensive, or, the more flexible solution involving automatic harmonization of indexing formulae based on pre established concordance tables. However, structural incompatibilities between post coordinated languages and classifications may lead any harmonization tools up a blind alley, while the paths of a universal concordance model are rare and narrow

- Abstract
- The creation of electronic information in the form of structured documents is gaining popularity. It is thus necessary to develop information retrieval tools fitted to this type of document. Presents the results of a research project aimed at identifying human-computer interface elements that can support information retrieval in structured-document bases. The research included a review of the literature and of existing systems, as well as the design, development, and user testing of a prototype information retrieval system for SGML document bases. Makes 5 recommendations for the design of structured-retrieval systems

- Abstract
- Since its appearance in the early 90's, the World Wide Web (WWW or Web) has provided universal access to knowledge and the world of information has been primarily witness to a great revolution (the digital revolution). It quickly became very popular, making it the largest and most comprehensive database and knowledge base thanks to the amount and diversity of data it contains. However, the considerable increase and evolution of these data raises important problems for users, in particular for accessing the documents most relevant to their search queries. In order to cope with this exponential explosion of data volume and facilitate their access by users, various models are offered by information retrieval systems (IRS) for the representation and retrieval of web documents. Traditional SRIs use simple keywords that are not semantically linked to index and retrieve these documents. This creates limitations in terms of the relevance and ease of exploration of results. To overcome these limitations, existing techniques enrich documents by integrating external keywords from different sources. However, these systems still suffer from limitations that are related to the exploitation techniques of these sources of enrichment. When the different sources are used so that they cannot be distinguished by the system, this limits the flexibility of the exploration models that can be applied to the results returned by this system. Users then feel lost to these results, and find themselves forced to filter them manually to select the relevant information. If they want to go further, they must reformulate and target their search queries even more until they reach the documents that best meet their expectations. In this way, even if the systems manage to find more relevant results, their presentation remains problematic. In order to target research to more user-specific information needs and improve the relevance and exploration of its research findings, advanced SRIs adopt different data personalization techniques that assume that current research of user is directly related to his profile and / or previous browsing / search experiences.
However, this assumption does not hold in all cases, the needs of the user evolve over time and can move away from his previous interests stored in his profile. In other cases, the user's profile may be misused to extract or infer new information needs. This problem is much more accentuated with ambiguous queries. When multiple POIs linked to a search query are identified in the user's profile, the system is unable to select the relevant data from that profile to respond to that request. This has a direct impact on the quality of the results provided to this user. In order to overcome some of these limitations, in this research thesis, we have been interested in the development of techniques aimed mainly at improving the relevance of the results of current SRIs and facilitating the exploration of major collections of documents. To do this, we propose a solution based on a new concept and model of indexing and information retrieval called multi-spaces projection. This proposal is based on the exploitation of different categories of semantic and social information that enrich the universe of document representation and search queries in several dimensions of interpretations. The originality of this representation is to be able to distinguish between the different interpretations used for the description and the search for documents. This gives a better visibility on the results returned and helps to provide a greater flexibility of search and exploration, giving the user the ability to navigate one or more views of data that interest him the most. In addition, the proposed multidimensional representation universes for document description and search query interpretation help to improve the relevance of the user's results by providing a diversity of research / exploration that helps meet his diverse needs and those of other different users. This study exploits different aspects that are related to the personalized search and aims to solve the problems caused by the evolution of the information needs of the user. Thus, when the profile of this user is used by our system, a technique is proposed and used to identify the interests most representative of his current needs in his profile. This technique is based on the combination of three influential factors, including the contextual, frequency and temporal factor of the data. The ability of users to interact, exchange ideas and opinions, and form social networks on the Web, has led systems to focus on the types of interactions these users have at the level of interaction between them as well as their social roles in the system. This social information is discussed and integrated into this research work. The impact and how they are integrated into the IR process are studied to improve the relevance of the results.

- Abstract
- Demonstrates how the efficiency of online searching can be increased the application of conceptual logic; which consists of making systematically explicit all the notional, semantic, and cognitive elements contained in the subject to be searched. Unlike a thesaurus, which has been designed for the most probable, multiple uses, conceptual logic makes it possible to access information through means fully adapted to specific uses. Examples are presented from the TOPIC information retrieval software

- Abstract
- Analyzed a special type of man-mchine interaction, that of searching an information system with natural language. A model for full text processing for information retrieval was proposed that considered the system's users and how they employ information. Describes how INIST (the National Institute for Scientific and Technical Information) is developing computer assisted indexing as an aid to improving relevance when retrieving information from bibliographic data banks
