In this paper we study user behavior in online dating, in particular the differences between the implicit and explicit user preferences. The explicit preferences are stated by the user while the implicit preferences are inferred based on the user behavior on the website. We first show that the explicit preferences are not a good predictor of the success of user interactions. We then propose to learn the implicit preferences from both successful and unsuccessful interactions using a probabilistic machine learning method and show that the learned implicit preferences are a very good predictor of the success of user interactions. We also propose an approach that uses the explicit and implicit preferences to rank the candidates in our recommender system. The results show that the implicit ranking method is significantly more accurate than the explicit and that for a small number of recommendations it is comparable to the performance of the best method that is not based on user preferences.

Data mining is a process of discovering patterns in large data sets involving methods at the intersection of machine learning , statistics , and database systems. The term “data mining” is a misnomer , because the goal is the extraction of patterns and knowledge from large amounts of data, not the extraction mining of data itself. The book Data mining: Practical machine learning tools and techniques with Java [8] which covers mostly machine learning material was originally to be named just Practical machine learning , and the term data mining was only added for marketing reasons.

The actual data mining task is the semi-automatic or automatic analysis of large quantities of data to extract previously unknown, interesting patterns such as groups of data records cluster analysis , unusual records anomaly detection , and dependencies association rule mining , sequential pattern mining. This usually involves using database techniques such as spatial indices.

These patterns can then be seen as a kind of summary of the input data, and may be used in further analysis or, for example, in machine learning and predictive analytics. For example, the data mining step might identify multiple groups in the data, which can then be used to obtain more accurate prediction results by a decision support system.

Neither the data collection, data preparation, nor result interpretation and reporting is part of the data mining step, but do belong to the overall KDD process as additional steps. The difference between data analysis and data mining is that data analysis is used to test models and hypotheses on the dataset, e. The related terms data dredging , data fishing , and data snooping refer to the use of data mining methods to sample parts of a larger population data set that are or may be too small for reliable statistical inferences to be made about the validity of any patterns discovered.

These methods can, however, be used in creating new hypotheses to test against the larger data populations. In the s, statisticians and economists used terms like data fishing or data dredging to refer to what they considered the bad practice of analyzing data without an a-priori hypothesis. The term “data mining” was used in a similarly critical way by economist Michael Lovell in an article published in the Review of Economic Studies in The term data mining appeared around in the database community, generally with positive connotations.

Social media mining is the process of obtaining big data from user-generated content on social media sites and mobile apps in order to extract patterns, form conclusions about users, and act upon the information, often for the purpose of advertising to users or conducting research. The term is an analogy to the resource extraction process of mining for rare minerals. Resource extraction mining requires mining companies to sift through vast quantities of raw ore to find the precious minerals; likewise, social media mining requires human data analysts and automated software programs to sift through massive amounts of raw social media data in order to discern patterns and trends relating to social media usage, online behaviours, sharing of content, connections between individuals, online buying behaviour, and more.

These patterns and trends are of interest to companies, governments and not-for-profit organizations, as these organizations can use these patterns and trends to design their strategies or introduce new programs, new products, processes or services.

As the internet dating market continues to grow, online matching services are a higher amount of creativity up-front with more power in terms of data mining.

Chris McKinlay was folded into a cramped fifth-floor cubicle in UCLA’s math sciences building, lit by a single bulb and the glow from his monitor. The subject: large-scale data processing and parallel numerical methods. While the computer chugged, he clicked open a second window to check his OkCupid inbox. McKinlay, a lanky year-old with tousled hair, was one of about 40 million Americans looking for romance through websites like Match.

He’d sent dozens of cutesy introductory messages to women touted as potential matches by OkCupid’s algorithms. Most were ignored; he’d gone on a total of six first dates.

With the approach of Valentine’s Day, I have some online dating related amusing news and sleazy bad news for you. Unlike most online dating sites that keep their data of users’ flirtations a secret, the free online dating site OKCupid data mines its database of over 1 million dating profiles to find interesting correlations to publish in its OKTrends series. The company does remove all personal identifiers to preserve users’ privacy and to keep the data anonymous, but its privacy policy advises users to be cautious about disclosing personal information that, once made public, can be “read, collected, or used by other users.

Like So while pursuing a Ph. How do you feel about tattoos; what is more offensive: book burning, or flag burning; how often do you mediate? To name a few of the thought-provoking and life inquests. McKinlay was chiefly interested in how members answered these questions. Do they tend to answer uniformly? Do their answers percolate throughout the space, similar if they answered by flipping a coin?

Or, do they clump around commonly held belief systems, and if so, by how much? Rolling up his sleeves, McKinlay determined that OkCupid members in the LA area at the time clustered into seven different groups, or user segments. Suddenly, he was the number-one match for more than 30, women — receiving approximately 88 unsolicited messages a week. By comparison, a straight male on OkCupid, the median number of unsolicited messages is zero. Going on an average of one date a day, McKinlay vowed to keep the project alive until either one of two things happened: OkCupid shut him down or he met someone worth ending the project for.

His reverse engineering algorithm immediately impacted his conversion rate from first-match to date. Today, McKinlay is engaged to Christine, a woman he met during his mathematical, and algorithmic, journey.

Knowledge Discovery is the most desirable end-product of computing. Finding new phenomena or enhancing our knowledge about them has a greater long-range value than optimizing production processes or inventories, and is second only to task that preserve our world and our environment. It is not surprising that it is also one of the most difficult computing challenges to do well. The main objective of knowledge discovery in Data Mining lies in the finding of data patterns.

The knowledge about the current customers can be used to predict profitable customers based on their personal information. This explorative report focuses on analysing different methods of data mining to predict profitable customers of a dating site. The second key aspect is to match individual customers based on their personal information. The dataset contains static activity and dynamic activity.

Static activity includes all personal, demographic and interest information entered by the customer at its registration. The emails sent, channels communicated and kisses sent describe the dynamic activity. Table 1 shows the customer details in the table. Another data table holds the information for users without stamps.
