The invention belongs to the technical field of computers, and particularly relates to a topic detection method and device for case-related public opinions. The topic detection method for the case-related public opinions comprises the steps of obtaining public opinion text data containing case public opinion texts; based on predetermined case element information and the position of the keyword inthe case public opinion text, determining an additional weight of the keyword; obtaining text vector representation of the public opinion text data according to the additional weight and a basic weight determined based on a TFIDF algorithm; conducting dimensionality reduction on the text vector representation through an auto-encoder, and obtaining low-dimensional text vector representation; and based on the low-dimensional text vector representation, clustering by adopting a spectral clustering algorithm to determine topics of the case public opinion text. When topic detection is carried out through the method, the detection efficiency and the detection accuracy are high, and the public opinions involved in the case can be captured in time.

The invention relates to a vehicle caller ID informing device for a mobile phone, and is formed by mutually connecting a mobile phone caller ID indicator, a photoelectric coupler, a voice record-play module, a three-terminal voltage regulator, a third capacitor C3, a switch K, speakers and a power supply. Therefore, the vehicle can capture phone caller ID signals in time in a noisy environment and inform mobile phone users in time, so as to prevent the omission of phone-answering.

The invention discloses a snakehead aquaculture method which comprises the followings steps that an anti-bacterial liquid is prepared: Chinese herbal medicines radix zanthoxyli, honeysuckle, dandelion, rheum officinale, pseudo ginseng, ginseng and lithospermum erythrorhizon are taken and added to water for boiling, then the Chinese herbal medicines are taken out, smashed and boiled continuously, and the anti-bacterial liquid is obtained; the water is boiled and cooled to the temperature of 30-40 DEG C; snakehead fry is put into water containing the anti-bacterial liquid for pre-aquaculture; aquaculture water is fed into a culture pond, and ultraviolet lamp irradiation sterilization is performed; the snakehead fry is put into the culture pond, and the anti-bacterial liquid is added to the culture pond every 30-40 days; aquaculture bait is put into the culture pond, the snakehead fry is bred into adult fish, and the aquaculture bait is put for three times everyday. According to the snakehead aquaculture method, the survival rate of the snakehead fry can be effectively improved, and the snakehead yield is improved.
