## 3 Urdu Web Queries Dataset (UWQ-22)  
The Urdu web queries dataset is the first dataset comprising of native web queries extracted from a localized platform. This section discusses in detail the dataset development and the intent annotation process.  
The Urdu web queries dataset has been extracted from the search records of Humkinar, an Urdu search engine [4], covering user queries from 1 st December 2020 till 31 st January 2021. Each search record tuple consisted of the following five fields: (i) a user identification number, (ii) user query, (iii) clicked URL, (iv) total time (in seconds) spent by the user on the clicked URL and (v) server time (in hours, minutes and seconds and the date). The user identification number, user query and clicked URL have been retained in this dataset. The total number of search records extracted from the search engine was 13,785. Search records with missing entries were removed and the final dataset comprised of 11,751 search records from 165 users. Table 1 describes the prominent statistics of the Urdu web queries dataset. The total queries in the dataset comprised of 42,214 terms, of which 38,789 were unique. The mean length of the web queries is 3.78 terms. The queries included in the dataset cover 11 domains [1]. Table 2 presents the domain-wise distribution of the queries with the respective number of terms.  
Table 2 highlights a balanced coverage of queries across all domains. The highest number of queries in the dataset were from entertainment, i.e., 1253 (11%), while queries related to the geography domain were the lowest, i.e., 964 queries (8%). A similar analysis over the AOL query domains was reported in [33] regarding Turkish and English datasets,

Table 2: Domain-wise distribution of Urdu web queries.  
where the highest number of queries, 19.9% and 12.6% in the respective datasets also fall in the entertainment category.  
As presented in Table 1, the mean length of the queries was 3.78 terms. Figure 1 describes the frequency distribution plot of the web queries with respect to query length. Figure 1 shows that the length of the web queries in the dataset ranged between 1 and 39 terms. Of those queries, 82.39% had less than or equal to five terms. Additionally, after a query length = 6, the frequency of queries started declining, reducing to a very low frequency after a query length = 10.  
Table 3 describes the mean query length with respect to query domains. It can be observed that the highest mean query length across all domains was for travel domain queries, i.e., 4.1 terms, while the lowest mean query length was of books and entertainment queries, i.e., 3.4 terms. It is interesting to note that the shopping domain had the longest query in the dataset (max. length 38 terms) while all domains include 1 word queries in the dataset.
