Question 1 (Index Construction):
Suppose you have joined a search engine development team to design a search algorithm based on both the Vector model and the Boolean model.
You have collected the following documents (unstructured) and plan to apply an index technique to convert them into an inverted index.

Doc 1：data science is field to use scientific method, process, algorithm, system to extract knowledge.

Doc 2：data mining is the process to discover pattern in large data to involve method at the database system.

Doc 3：information system is the study of network of hardware and software that people use to process data.

To answer the below questions, you have to provide the detailed procedures step by step.
You need to remove all stop words and punctuation before the process of creating the inverted index. After that, please complete the following steps:

Question 1.1:
Create a merged inverted list including the within-document frequencies for each term.

Question 1.2:
Use the index created as above to create a dictionary and the related posting file.

Question 1.3:
Please design three Boolean queries, (for example, web AND search) and list the relevant documents for each query. Each query must contain at least two keywords while no one keyword appears in one document only.

Question 1.4:
Please use the Vector model to query on the inverted index, and compare the result with the Boolean model. (Hint: you can use cosine similarity and set a similarity threshold).

Var add = function( x, y ) { return ( x + y ); } alert( add (5, 3) ); 11. (refer to code example 2.) the function a. accepts 2 parameters and returns 2 values. b. accepts 2 parameters and returns 1 value. c. accepts 2 parameters and does not return a value. d. does not accept a parameter and returns 1 value.

In this lab, you complete a prewritten c++ program for a carpenter who creates personalized house signs. the program is supposed to compute the price of any sign a customer orders, based on the following facts: the charge for all signs is a minimum of $35.00. the first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. if the sign is made of oak, add $20.00. no charge is added for pine. black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering. instructions ensure the file named housesign.cppis open in the code editor. you need to declare variables for the following, and initialize them where specified: a variable for the cost of the sign initialized to 0.00 (charge). a variable for the number of characters initialized to 8 (numchars). a variable for the color of the characters initialized to "gold" (color). a variable for the wood type initialized to "oak" (woodtype). write the rest of the program using assignment statements and ifstatements as appropriate. the output statements are written for you. execute the program by clicking the run button. your output should be: the charge for this sign is $82. this is the code, // housesign.cpp - this program calculates prices for custom made signs. #include #include using namespace std; int main() { // this is the work done in the housekeeping() function // declare and initialize variables here // charge for this sign // color of characters in sign // number of characters in sign // type of wood // this is the work done in the detailloop() function // write assignment and if statements here // this is the work done in the endofjob() function // output charge for this sign cout < < "the charge for this sign is $" < < charge < < endl; return(0); }

How do i get the most points, without any effort?
