Purposes To describe the rationale, surgical technique, and short-term follow-up results of a new minimally invasive treatment for thoracic spinal stenosis (TSS) caused by herniation, ossification of the ligamentum flavum (OLF), and/or ossification of the posterior longitudinal ligament (OPLL) with a “U” route transforaminal percutaneous endoscopic thoracic discectomy (PETD). Methods Fourteen patients,...
This paper proposes a word sense disambiguation algorithm based on How Net. This algorithm makes full use of abundant instances library which provided by How Net to carry on preliminary disambiguation. If it does not match with the database, then the algorithm will extract the keywords inherent defined to ambiguities through the dependency grammar. Finally, combined with the explicit and implicit...
Automatic error detection and correction of text is an important research area of natural language processing. Studies abroad originated in 1960s on automatic text error detection and correction. Since the 1990s, many academic studies on automatic text error detection and correction have been made in China. This paper analyzes the state of the art of the automatic check and correct approaches for...
In this paper, we introduce a classification approach for Uighur web pages. It utilizes the class feature dictionary and Cosine similarity computation to classify the Uighur web pages into the predefined classes rapidly and accurately. The experimental result shows that the approach has a good classification performance for Uighur web pages classification. It is useful and helpful for the construction...
Recently, emergency early warning is a popular research area, the purpose of which is to prevent outbreak of the events endangering social stability. To establish the corpus of university emergency is the first step of the research. The paper discusses the current situation of the corpus. Then, we give the classification system of the university emergency. In the paper, we propose the basic framework...
In this paper, mainly discuss study on basic vocabulary in terms of characteristics of all the people used, the time stability and the words formation ability based on the dynamic circulating corpus of modern Chinese in mass media, structure the automatic identification and retrieval model of "Contemporary Chinese Basic Vocabulary for Language Engineering" CBVE, realize automatic extraction...
The knowledge-based information extraction approach has been proved effectively in the recognition and classification of Web texts. Manual creation of knowledge base is time consuming and error prone, even for a small application domain. For improving the automatic construction ability of knowledge base in the process of IE, this paper presents a web text extraction tool based on case similarity calculation...
As the internet grows dramatically and the information is exploding, natural language processing is playing more and more important role to obtain useful knowledge quickly. China is rich in language resources, so we need to invest considerable effort to gather and process these languages. However, researches on Chinese minority languages processing is very inadequate. It is disadvantageous to promote...
