Meaning, the arguably most important theoretical object of study in information access, is most decidedly situationdependent. While much of meaning appears to achieve consistency across usage situations — a term will seem to mean much the same thing in many of its contexts — most everything can be negotiated on the go. Human processing appears to be flexible in this respect, and oriented toward...

noindent This paper describes the World Wide Web Index and Search Engine (WISE) for resource discovery. The system is designed around a resource database containing meta-information about WWW resources and is automatically built using an indexer robot, a special WWW client agent. The resource database allows users to search for resources based on keywords, and to learn about potentially relevan...

In this paper, we report on the usage of Japanese segmented texts and analyze the submitted search results to NTCIR Workshop 2, which used these texts. In these texts, each sentence is segmented into terms and term components (similar to phrases and words). However, the sizes of terms are inconsistent in the texts; e.g., some terms that should be decomposed into term components remain as terms....

• Recognition of logical document structures [1], where knowledge of the font used in a word, line, or text block may be useful for defining its logical label (chapter title, section title or paragraph). • Document reproduction, where knowledge of the font is necessary in order to reproduce (reprint) the document. • Document indexing and information retrieval, where word indexes are generally p...

Information Retrieval models, which do not represent texts merely as collections of the words they contain, but rather as collections of the concepts they contain through synonym sets or latent dimensions, are known as Bag-of-Concepts (BoC) representations. In this paper we use random indexing, which uses co-occurrence information among words to generate semantic context vectors and then repres...

Other research has shown that although the abstract is more information dense, the full text of a scientific article in the biomedical domain has much greater information content.1 We know from observing indexers and studying their indexing process that some of the assigned MeSH concepts do not appear in the abstract. The indexing manual also dictates that the abstract should not be used during...

In our information era, keywords are very useful to information retrieval, text clustering and so on. News is always a domain attracting a large amount of attention. However, the majority of news articles come without keywords, and indexing them manually costs highly. Aiming at news articles’ characteristics and the resources available, this paper introduces a simple procedure to index keywords...

This paper proposes a generational accounting approach to valuating research. Based on the flow of scientific results, a value-added (VA) index is developed that can, in principle, be used to assign a monetary value to any research result and, by aggregation, on entire academic disciplines or sub-disciplines. The VA-index distributes the value of all applications that embody research to the wor...
