Abstract

With the development of computer retrieval technology, how efficient computer retrieval technology to replace the heavy ancient literature search, the computer has become an important practical issue retrieval theory, but also ancient figures Chemical author goal. Among the many types of ancient literature, ancient Chinese literature has a special historical position, it is the technology of modern medicine an important basis for the development of research, is the source of Chinese culture, is the maximum utilization of a class of ancient literature. Therefore, the Chinese ancient literature retrieval system research has important practical significance and academic significance, the protection of Chinese ancient literature also played a positive role. 80s from the 20th century, workers have made a lot of literature digitization finishing work. But in ancient Chinese literature organization organize or retrieval system is established, the type found in many ancient Chinese literature, how to organize and how to use the literature have tidied ancient literature is to build one of the key literature retrieval systems. Therefore, this study proposes a case based on the ancient literature to divide the data type. That is, not finishing for the origin of literature data, finishing a very complete data for the topic, the ancient literature of indexing for indexing data, there are some pictures in the form of data is called the origin of the image data. Chinese ancient literature retrieval systems research is mainly the organization of ancient literature data storage and retrieval two aspects of research. Storage, the main consideration how to design a database to meet the characteristics of ancient literature. Four types of data in the literature of ancient origin, the design of the database structure to become a difficulty, because the ancient literature of the genre is varied, how different genres of literature stored in the same database structure is more difficult. After the study found that although the genre of ancient literature is diverse, but the bibliography perspective, no matter what the genre has a clear directory level, so this study in order to break the conventional literature content into the field of database design model, and changed to a directory level to divide the database structure, this database structure can all genres of ancient literature data can be stored in a database. In the retrieval, we should consider what kind of search strategies and browsing search results to adapt the characteristics of ancient literature. In addition to the general search strategy retrieved on a retrieval system, secondary search, retrieval and other combinations, this study adds to the semantic search and retrieval after control. Semantic retrieval system based on the user's search terms will contain the same semantics to all content retrieved; later retrieval is to control the retrieval and natural language information retrieval language combine effective control of the search range. Semantic search and retrieval after control greatly improves the utilization of ancient literature precision and recall. In the search results browsing research, in addition to general browsing, the study also achieved a summary of browsing and paragraphs browsing. Abstract browse, that is generated around the search word summary of search results in the form of browsing; paragraphs browsing, namely to show only paragraphs where the search term in the form of browsing. In this paper, ancient Chinese literature search and the proposed design of the database, search strategies, and browse presentation methods, the experiment shows that has a certain nature, compatible with all kinds of ancient documents, can improve the precision and recall, to facilitate retrieves the user retrieval result output of the various requirements.
