The search effect of Sina Weibo in different demand scenarios is studied, and optimization schemes are proposed to meet the needs of users to obtain information efficiently.
2. Research and Analysis
Referring to the way of thinking about web search strategy, we will analyze the shortcomings of Weibo search from the clarity of needs, query characteristics and requirements for results:
Analysis of search results:
The search results meet the basic needs of users. The first one is an introduction to the movie "My Neighbor Totoro". From the second to the fourth, there are comments from well-known bloggers, but the information further down only contains the word "My Neighbor Totoro". , such as complaints from celebrities and bloggers, daily statements, and bloggers’ video recommendations, but there is no other valid information about “My Neighbor Totoro”.
It can be seen from the query that Weibo has performed word segmentation on the search words (some do not contain the word "movie"), but has country email list not performed corresponding semantic analysis. In the first 4 pieces of information, the popularity and relevance are high, which can meet the needs of most users, but in the latter information, as long as there are relevant keywords in the query word that match the latest news, the system will Ranking the information, which leads to a decrease in relevance and a situation where the push results do not match the user's expectations.
Scene 2: Search for "Actor Song Joong Ki"
Search term: Actor Song Joong Ki
Expecting Results: The Latest on Song Joong Ki
Actual results show:
Analysis of search results: The search results basically meet the needs of users. The first one is popular on official Weibo, which is the latest news of Song Joong-ki and meets the needs. Looking further down, most of the information still meets the needs, but there is also the problem of word segmentation. For example, the blogger's daily statement contains the word "Song Zhongji", but there is no other valid information. This is also a query word segmentation. Matching problem, this is problem one.
In addition, a large number of duplicate information under each topic has not been systematically screened, which increases the cost for users to obtain differentiated information. For example, the film "Bogota" starring Song Joong-ki has been suspended. This news was reported by different bloggers. Continuous and frequent push, this is the second problem.
