Ignoring attributes (these are related to semantic aspects that can be treated separately from purely structural aspects which interest us here), in the context of a cooperative edition, legal structures are characterized by a document model (an abstract grammar) and each intentional representation can be manipulated independently and eventually asynchronously by several co-authors through various editing tools that operate on its “partial replicas”. For unsynchronized edition of a partial replica, considered co-author must have a syntactic document local model that constraints him to ensure minimum consistency of local representation that handles with respect to the global model. This consistency is synonymous with the existence of one or more (global) intentional representations towards the global model, assuming the current local representation as her/their partial replica. The purpose of this paper is to present the grammatical structures which are grammars that permit not only to specify a (global) model for documents published in a cooperative manner, but also to derive automatically via a so call projection operation, consistent (local) models for each co-authors involved in the cooperative edition. We also show some properties that meet these grammatical structures.展开更多

When the document is short, e.g. only the abstract is available, the word-use variability problem will have substantial impact on the Information Retrieval （IR） performance. To solve the problem, a new technology to short document retrieval named Reference Document Model （RDM） is put forward in this letter. RDM gets the statistical semantic of the query/document by pseudo feedback both for the query and document from reference documents. The contributions of this model are three-fold： （1） Pseudo feedback both for the query and the document; （2） Building the query model and the document model from reference documents; （3） Flexible indexing units, which can be ally linguistic elements such as documents, paragraphs, sentences, n-grams, term or character. For short document retrieval, RDM achieves significant improvements over the classical probabilistic models on the task of ad hoc retrieval on Text REtrieval Conference （TREC） test sets. Results also show that the shorter the document, the better the RDM performance.展开更多
