Abstract

The present invention discloses a full-text retrieval device for an interactive electronic technical manual of shipping equipment. The full-text retrieval device comprises a common source database, a specialized vocabulary extraction module, an abbreviation extraction module, a first segmentation module, a technical information term database, an equipment part name database, an abbreviation database, a general vocabulary database, a retrieval record database, a user retrieval command communication module, a retrieval module, a second segmentation module, an index database and an index module. Element label characteristics and document content in data module documents are composited, query is carried out by utilization of specialized vocabularies, weight of the specialized vocabularies in documents and retrieval keywords is increased, so that the system can carry out query in certain semantic levels, returned retrieved results are closer to retrieval intention of users, and therefore high recall rate and accuracy of the retrieval system are ensured.

Description

technical field [0001] The invention relates to the technical field of information retrieval, in particular to a full-text retrieval device and method for an interactive electronic technical manual of ship equipment. technical background [0002] At present, most of the technical data of ship equipment exist in paper form, which leads to increasingly heavy management tasks of technical data, increased data repetition rate and redundancy, and is difficult to update, and the interoperability, real-time transmission and sharing of data are difficult. In order to solve the above problems, an interactive electronic technical manual (IETM, Interactive Electronic Technical Manual) is usually compiled to manage technical data, that is, it is compiled in accordance with standard digital format standards, using text, graphics, tables, audio and video, etc., through human-computer interaction. Technical publications that provide the basic principles, operation and maintenance support o...
