example 1

[0118] The time of crime is the time when the crime takes place, and the time when the criminal has to step on the spot and premeditate before stealing cannot be regarded as the time of crime. Similarly, in the case of intentional homicide and injury, the time when the conflict occurs or the motive for committing the crime occurs is not the time of committing the crime. The criminal time is generally the last time in the criminal process. For example: suppose the court documents have the following criminal process: the defendant Hu Feng and the victim Ma Moujia (17 years old) who was studying in Xinjiang met through QQ chat and developed a romantic relationship. After learning that their daughter Ma Moujia was in love early, Ma Moujia and his wife brought Ma Moujia back from Xinjiang to his home in Wudu in early March 2016. Ma Moujia proposed to Hu Feng to break up. At 8 o'clock on the 25th, I came to Maba Village, Hanwang Town, Wudu District, called Ma and asked for reconcili...

[0178] The aforementioned extraction of the criminals of the at least one criminal fact text block includes: obtaining the first set of criminals from the defendant; obtaining the second set of criminals from the criminals who are absconding or dealt with in another case through an information extraction model ; Deduplicating the offenders in the first set of offenders and the second set of offenders to obtain the offenders.

[0179] The process of extracting the offenders in the first crime set from the defendant and offenders who are dealt with separately will be illustrated below with reference to the criminal case judgment.

[0203] Most criminal cases involve money or amounts, such as the items involved in the theft and robbery cases, the cash involved, the stolen money, the compensation and economic losses in the homicide and injury cases, etc. Therefore, criminal cases need to withdraw the money involved. The embodiment of the present application adopts rule-based information extraction technology to extract funds involved in the case. In the embodiment of the present application, the range of information extraction is gradually narrowed based on locating text blocks layer by layer, so the accuracy of extraction can be greatly increased. For example, for the extraction of funds involved in a case, the economic loss text block can be located first, and then each expense category can be located from the economic loss text block.

[0204] The extraction of the money involved in the case of the at least one criminal fact, which is established in the present application, includes: extracting the cash...
