related to voice behavior (β transactional-voice=-0.381) and loyalty behavior(β transactional-
loyalty=-0.374), but it has no significant relationship with neglect behavior and exit behavior.
Finally, the relational psychological contract violation has a significant negative effect on
the voice behavior and loyalty behavior, and has a significant positive effect on the exit and
neglect behavior. This result is consistent with the conclusion that there is a negative correlation
between the employee’s psychological contract violation and the active working behaviors, and a
significant positive correlation with the negative work behaviors in the real organization situation.
It shows that whether in an entity organization or in a virtual community such as social reading,
the violation of relational psychological contract always has an important impact on individual
behaviors. In particular, the average of exit behavior (M exit=2.51) and the average of neglect
behavior (M neglect=2.85) are both greater than the middle level, indicating that it is common
for users to ignore messages, let APPs lie idle, or even directly abandon use in socialized reading
communities. This research not only enriches the related theories of psychological contract and
information behavior, but also has guiding significance for the sustainable development of various
stakeholders in the social reading business ecosystem.

Review of Web information retrieval based on temporal semantics

SHEN Si 〇, LI Chengming & WU Peng
Web information retrieval based on temporal semantics is widely applied in the retrieval scenarios
of dynamic temporal information mining, collective memory and temporal question answering
system. By fully utilizing the temporal information contained in the Web documents, we cannot
only retrieve the set of texts related to specified lexical semantics at a certain time point but also
identify the pattern of theme evolution of contents in each independent information carrier over
time. A total of 94 studies related to this topic are retrieved and analyzed. The Chinese search
words are“时态语义”“时间信息检索”“时间信息抽取”“检索模型”“深度学习”; the English
search words are “temporal semantic”, “temporal information retrieval”, “temporal information
extraction”, “retrieval model” and “deep learning”. The databases searched are Wanfang Database,
CNKI, PQDD-ProQuest Digital Dissertation, ISI Web of Knowledge, Elsevier ScienceDirect,
Academic Source Premier-EBSCO, LISA, SpringerLink and EI-Engineering Village 2. The
extraction and labeling of text’s temporal information and the retrieval model incorporated with
temporal information are used. Existing studies are classified by comparison and content analysis
and are reviewed in terms of each step of information retrieval in the narrow sense. Related
researches in three aspects, namely, implicit temporal intention analysis in information requirement,
construction of retrieval model incorporated with temporal factors, and promotion of retrieval
