Keyword-based web query languages suffer from a lack of precision when searching for a precise kind of documents. Indeed, some documents cannot be simply characterized by a list of keywords. For example, searching for on-line pictures dealing with formula one using only simple keywords with general-purpose search-engines gives imprecise answers. This imprecision is due to the method that consid...

-An algorithm is presented for keyword recognition in Oriental language document images. The objective is to recognize keywords composed of more than one consecutive character in document images where there are no explicit visually defined word boundaries. The technique exploits the redundancy expressed by the difference between the number of possible character strings of a fixed length and the...

In this paper, we present a method of applying Independent Topic Analysis (ITA) to increasing the number of document data. The number of document data has been increasing since the spread of the Internet. ITA was presented as one method to analyze the document data. ITA is a method for extracting the independent topics from the document data by using the Independent Component Analysis (ICA). IC...

This paper addresses the problem of enhancing document retrieval under the specific restrictions posed by the Question Answering scenario. In particular, given an input question, we aim at defining a reliable method for expanding its keywords with semantic information extracted from WordNet (e. g. synonyms or hypernyms). This is a challenging task, since it is intrinsically dependent on high qu...

There are many governmental, cultural, commercial and educational organizations that manage large number of manuscript textual information. Since the management of information recorded on paper or scanned documents is a hard and time-consuming task, Document Image Analysis (DIA) aims to extract the intended information as a human would (Nagy, 2000). The main subtasks of DIA (Mao et al. 2003) ar...

The multimedia information retrieval from World Wide Web is a challenging issue. Describing multimedia object in general, images in particular with low-level features increases the semantic gap. From WWW, information present in a HTML document as textual keywords can be extracted for capturing semantic information with the view to narrow the semantic gap. The high-level textual information of i...

the study discusses the traditional and online procedures and outlines of sdi service. the paper has also taken an initiative to formulate an exact matching technique between user’s subject interest and document profile with exploration along with electronic delivery of voluminous information technique. it also discusses some standard features and model of user profile. finally, the paper explo...

The paper presents a tool for keyword extraction from multilingual resources developed within the AXMEDIS project. In this tool lexical collocations (Sinclair, 1991) internal to documents are used to enhance the performance obtained through standard statistical procedure. A first set of mono-term keywords is extracted through the TF.IDF algorithm (Salton, 1989). The internal analysis of the doc...
