Embodiment 1
[0028] This embodiment proposes an ontology-based search intent expression method, such as figure 1 As shown in FIG. 2 , it is a flow chart of the method for expressing search intent in this embodiment.
[0029] The search intent expression method proposed in this embodiment includes the following steps:
[0030] S1. Obtain the search content input by the user, and perform word segmentation on the search content.
[0031] S2. Use the preset domain ontology-based knowledge graph to identify the concept of the word segmentation result, and obtain the concept label corresponding to the word segmentation result.
[0032] S3. According to the concept label corresponding to the word segmentation result, search for synonyms, extension words and / or associated words from the domain ontology-based knowledge graph and display them.
[0033] S4. The user selects a target search word from the displayed synonyms, extension words and / or associated words, and combines the selected target se...
Embodiment 2
[0040] This embodiment proposes an ontology-based search intent expression method, such as image 3 As shown in FIG. 2 , it is a flow chart of the method for expressing search intent in this embodiment. It includes the following steps:
[0041] S1. Obtain the search content input by the user, and perform word segmentation on the search content.
[0042] In this step, search content such as keywords, logical combinations of keywords, sentences, and texts input by the user is divided to obtain word segmentation results, which are used for further concept recognition and search intent generation.
[0043] S2. Use the preset domain ontology-based knowledge graph to identify the concept of the word segmentation result, and obtain the concept label corresponding to the word segmentation result.
[0044] In this embodiment, the domain ontology in the domain ontology-based knowledge graph includes concept sets, attribute sets, individual sets, and fact sets; wherein, the attribute set...
Embodiment 3
[0065] This embodiment proposes an ontology-based search intent expression system, using the search intent expression method proposed in Embodiment 1 or Embodiment 2. Such as Figure 4 Shown is the architecture diagram of the search intent expression system of this embodiment.
[0066] The search intent expression system proposed in this embodiment includes a human-computer interaction module, a word segmentation module, a knowledge map module, a concept recognition module, a recommended word generation module, and a search intent expression generation module.
[0067] Wherein, the word segmentation module is used for word segmentation of the search content acquired by the human-computer interaction module.
[0068] The knowledge graph module stores a preset domain ontology-based knowledge graph. The domain ontology in the knowledge graph includes concept sets, attribute sets, individual sets and fact sets. Wherein, the attribute set includes data attributes and object attr...
