Definitions
- the invention relates to a method for generating a city cognitive map, in particular to a method for generating an urban cognitive map based on internet word frequency, which belongs to the field of cognitive map generation.
- Kevin Lynch believes that urban imagery is the result of the interaction between the urban environment and the observers, emphasizing the perception of the citizens and the urban experience. It is intended to construct the spatial structure of the city through the elements of the city image “roads, borders, regions, nodes, markers”. . Since Kevin Lynch used the cognitive map method to analyze the urban imagery in Boston, the research on urban cognition in the field of planning and design has gradually increased, but the research and planning surveys basically follow the method of small-scale sampling survey, that is, through Questionnaire surveys and cognitive maps were drawn from small sample populations to obtain image cognition within the city or region. With the rapid development of information technology, new media such as the Internet have greatly affected the perception of citizens' cities. The data traffic generated by social activities has risen sharply.
- Baidu maps Under the popularity of Baidu maps, citizens can recognize cities on the Internet, both at home and abroad. Scholars have also done some research in this area. Zhao Yuxi (2015) and other network images are used as empirical analysis objects to compare the image representations of different cities in the Internet. Li Wei (2009) believes that the new cognitive maps obtained by using network data analysis are reflections on the image of Internet social cities. It also enriches the technical means of planning research to a certain extent.

Attribute”, the frequency of the added words is the new traffic cost attribute; the editor uses the "road recognition word frequency” field as the way of calculating the traffic cost, and is set to be used by default, click to generate a new network data set and load it into the map;
- the present invention uses the Baidu network word frequency of place names and roads as a basis to quantitatively recognize the three elements of a city's location, intersection (point), road section (line), and block (face). Analysis, find out the road segments and regions with high urban network awareness, generate city cognitive maps of points, lines and planes, thus changing the cognitive style of the city, reconstructing the cognitive image of the city, in order to seek the city A more accurate understanding of space is a complement to traditional urban spatial cognition methods.

- This embodiment is an application example. Taking the urban area of Wuning County, Jiujiang City, Jiangxi province as the research object, the method of the above embodiment 1 is practiced, and a new urban spatial cognition is proposed from a network perspective by using big data and small samples. Traditional urban imagery forms a complementary relationship and also perfects the city. Planning the investigation system.
- the collected word frequency data is assigned to intersections, road sections and blocks according to certain regulations, and a cognitive map based on network word frequency is generated.
- the size of the intersection points indicates the word frequency of the intersection, and the intersection is affected by the word frequency of the road connected to it at the same time.
- the intersection with higher degree of attention is concentrated in the east of Renmin Road and the west of Yuning Avenue in the old town of Wuning County. It can be seen that the recognition of the old city is still relatively high. Due to the increase in the construction of the new city, the attention of the new city has also begun to rise.
- the thickness of the road indicates the degree of attention of the road segment. It can be seen from the analysis in the figure that the roads in the Wuning County Expressway, Provincial Highway, Xihai Bridge, Wuning Bridge and Yuning Old Town are of high concern. At the same time, Xihai Avenue has a relatively high degree of attention due to its beautiful scenery along the road.
- the word frequency heat has obvious central aggregation, the attention of the old city of Wuning County is higher, and the attention of the new city is lower. It may be because the number of places in the new city is less, the degree of construction is relatively new, and the network is accumulated. The number of entries is relatively low; the network has a high level of attention to basic public facilities such as transportation, political culture, etc. (flag construction/structure), followed by public spaces such as parks and plazas (locations).
- the present invention uses the Baidu network word frequency of place names and roads as a basis to quantitatively analyze the three elements of the city's location, intersection (point), road section (line) and street area (face).
- Urban roads with high awareness of the road segments and regions, generating point, line, and surface urban cognitive maps, thereby changing the way of understanding the city, reconstructing the cognitive image of the city, in order to A more accurate understanding of urban space is a complement to traditional urban spatial cognition methods.
