specific Embodiment

[0070] For the following piece of text data: "The ventilation function is the latest technology used in wall-mounted air conditioners to ensure fresh air in the home and prevent air-conditioning diseases... In addition, quiet and energy-saving design is also very important...The cooling and heating wall-mounted Type air conditioner, pay attention to choose the air conditioner whose heating capacity is greater than the cooling capacity to ensure the heating effect. If there is an electric auxiliary heating function, it can ensure that the heating can be performed in an ultra-low temperature environment (minimum -10 degrees Celsius)... "This The invention process is as follows:

[0071] The above description of the wall-mounted air conditioner comes from the Internet Encyclopedia website. It can be seen that the ability keywords are covered in this short text. Take the BIESO structure tagging method using five-digit words as an example (there are also four-digit words, six-digit ...

Abstract

The present invention discloses a capability knowledge extraction method, comprising: data collection, obtaining text data from the network and objects connected to the network; data recognition, processing the text data by using natural language processing methods; data understanding, according to The specific rules label the text data processed by natural language; data screening, extract and filter the ability knowledge of the labeled data through a variety of models; data induction, identify and summarize the labels in the filtered data, and then obtain ability knowledge. Also disclosed is a method for constructing a capability knowledge map, including: extracting a capability ontology through data collection, identification, understanding, screening, and inductive processes; using machine learning methods to learn the extraction process of the capability ontology; classifying and storing the knowledge ontology, and then Obtain a knowledge map of capabilities. The invention solves the problem of intercommunication and sharing of heterogeneous resources in the Internet of Things, and realizes the automation and intelligence of capability ontology extraction.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to a method for extracting capability knowledge and constructing a capability knowledge map. Background technique [0002] The Internet of Things is to connect various information sensing devices, such as radio frequency identification (RFID) devices, sensor networks, infrared sensors, global positioning systems, laser scanners, etc., to connect items to the Internet in accordance with agreed protocols through information exchange. , so as to realize a huge network formed by intelligent identification, positioning, tracking, monitoring and management. [0003] With the development of the Internet of Things technology, the types of Internet of Things devices have become more abundant, and the perception and control capabilities have been greatly improved. At the same time, the application of the Internet of Things has also been developed, but the system scale has become larger a...
