• Algorithms for pairing a rating system to an assignment queue

  - by blunders

  Attempting to research how to allow a group of people to effectively rank a set of objects (each group member will have contributed one object to the group), and then assign each member an object that's not their own based on: Their ratings of the objects, Their objects rating, and The object remaining to be assigned. Idea is to attempt to assign objects to people based on the groups rating of their contribution to the group relative to other member's contribution, the the personal preferences expressed via the ratings. Any suggestions for: Further research, Refining the statement of the problem/solution, or A solution.

• Algorithm for rating books: Relative perception

  - by suneet

  So I am developing this application for rating books (think like IMDB for books) using relational database. Problem statement : Let's say book "A" deserves 8.5 in absolute sense. In case if A is the best book I have ever seen, I'll most probably rate it 9.5 whereas for someone else, it might be just an average book, so he/they will rate it less (say around 8). Let's assume 4 such guys rate it 8. If there are 10 guys who are like me (who haven't ever read great literature) and they all rate it 9.5-10. This will effectively make it's cumulative rating greater than 9 (9.5*10 + 8*4) / 14 = 9.1 whereas we needed the result to be 8.5 ... How can I take care of(normalize) this bias due to incorrect perception of individuals. MyProposedSolution : Here's one of the ways how I think it could be solved. We can have a variable Lit_coefficient which tells us how much knowledge a user has about literature. If I rate "A"(the book) 9.5 and person "X" rates it 8, then he must have read books much better than "A" and thus his Lit_coefficient should be higher. And then we can normalize the ratings according to the Lit_coefficient of user. Could there be a better algorithm/solution for the same?

• How do I use this indirect relationship?

  - by tyjkenn

  I'm working on incorporating a reputation system into my site, similar to SO. Here is how it is structured: User hasMany Project User hasMany Answer Project hasMany Rating Answer hasMany Rating Rating belongsTo Project where Rating.parent_type = Project Rating belongsTo Answer where Rating.parent_type = Answer Rating's value field will be a number between 1 and 5. The user should gain +10 for every 5-star review, +5 for every 4-star review, and +1 for every 3-star review. The way I currently have it set up is this: a recalcRep($id) action in the UsersController (along with other actions in other controllers, when necessary) calls the calcRep($id) method inside the User model, which is supposed to calculate the reputation of a user with an id of $id. public function calcRep($id) { $rep = 0; $data = $this->Rating->find('all'); //does not work, because it is not directly associated foreach($data as $rating) { if(($rating['Rating']['parent_type'] == 'Project' && $rating['Project']['user_id']==$id) or ($rating['Rating']['parent_type'] == 'Answer' && $rating['Answer']['user_id']==$id)) { if($rating['Rating']['value']==5) { $rep += 10; } else if($rating['Rating']['value']==4) { $rep += 5; } else if($rating['Rating']['value']==3) { $rep += 2; } } } $data['User']['reputation'] = $rep; $this->save($data); } I may be approaching this in completely the wrong way, but I can't figure out how to find all the ratings that belong to any of the children of a specific user.

• Obtaining photo 'stars' rating using PHP

  - by DarwinIcesurfer

  I am trying to extract the photo 'stars' rating from .jpg files using php code. My intent is to show the highest rated images as part of a slideshow. I found that using the PHP_JPEG_Metadata_Toolkit_1.11 I am able to get the rating of the file if the rating is set from within Vista (Right click - Properties - Details - Set rating by clicking on stars) by reading the array returned by the Metadata_Toolkit $exif = get_EXIF_JPEG( $photodir . "/" . $filename ); $rating = $exif[0][18246]['Data'][0]; However if I set the rating using Adobe Bridge, I can see the 'stars' in Vista, but the $exif[0][18246]['Data'][0] returns a null value. Is PHP code available to read the ratings applied by both Windows Vista AND Adobe Bridge?

• Yelp Like Adjective Rating System

  - by clifgray

  I am building a website that has users list their outdoor adventures (skydiving, surfing, base jumping, etc) and the other people can comment on them. I want to have a rating system like Yelp which has "Useful, Funny, or Cool" but with different adjectives. I have thought of a few such as Daring, Adventurous, and Unique but I wanted to get some feedback on what a few other good adjectives would be. Also does anyone have experience with other such systems or advice for better systems? Primarily I just want the user to have somewhat more descriptive voting options than u and down or 1 though 5.

• Showing schema.org aggregate rating in Google rich snippets

  - by nickh

  After adding schema.org microdata markup for reviews and aggregate ratings, I expected review and rating information to show up in rich snippets. Unfortunately, neither are being shown. Google's Structured Data Testing Tool finds the microdata, and there're no errors or warnings on the page. Any idea what's wrong with the microdata markup? Example 1: Live Page: http://www.shelflife.net/ljn-thundercats-series-3/bengali Google Test: http://www.google.com/webmasters/tools/richsnippets?q=http%3A%2F%2Fwww.shelflife.net%2Fljn-thundercats-series-3%2Fbengali Example 2: Live Page: http://www.shelflife.net/star-wars-mighty-muggs/asajj-ventress Google Test: http://www.google.com/webmasters/tools/richsnippets?q=http%3A%2F%2Fwww.shelflife.net%2Fstar-wars-mighty-muggs%2Fasajj-ventress

• Google Keyword Competition rating

  - by Eric

  Google offers a Keyword application that allows me to see the number of time a particular query has been made in Google. There is a column in the results named "Competition" (Actually its Concurrence in French, I'm just translating). Its a rating from 0 to 1, as in percentage. What indicator is that? EDIT * Is this something useful I should rely on? I'm not sure about how to interpret this data. Should I go for less competitive keywords with a lower number of searches or not worry about it and go for the highly searched keywords anyway? Is 50% considered high? what about 75% ? I have a very niche market that sell expensive offline services, so the very long tail is my goal (I assume). If you didn't already figured out, I'm very new to SEO =)

• What framework for text rating site?

  - by problemofficer

  I want to start a "rate my"-style site. The rated objects are mostly texts. I want it to be rather simple. Features I need: object rating (thumb up, thumb down) object comments object tags related object presentation based on tags user authentication and management private message system sanity checks for text inputs (i.e. prevention of code injections) cache open source runs on GNU/Linux I would gladly take something that is tailored for my scenario but a generic framework would be fine too. I simply don't want to write stuff like user authentication that is been written a million times and risking security flaws. Programming language is irrelevant but python/php preferred.

• Android -- How to post app rating/comments to Market from within app?

  - by borg17of20

  Hello all, This is a simple question. Is there a way to allow users to enter in a comment and or rating for my app from directly within my app and have that data posted back to the Android Market? If so, what would the code for that look like if I used an EditText view to allow user input? If not, then is my only other option directly linking to my app in the Market (i.e. the user clicks the link in my app, or a button, and the Market app launches with my app page displayed)? For example: view.setOnClickListener( new OnClickListener(){ public void onClick(View v) { startActivity( new Intent( Intent.ACTION_VIEW, Uri.parse("market://details?id=packagename") ) ); } } *where "packagename" is replaced by my app's package name from the manifest. Thanks.

• What is a better way to sort by a 5 star rating?

  - by Vizjerai

  I'm trying to sort a bunch of products by customer ratings using a 5 star system. The site I'm setting this up for does not have a lot of ratings and continue to add new products so it will usually have a few products with a low number of ratings. I tried using average star rating but that algorithm fails when there is a small number of ratings. Example a product that has 3x 5 star ratings would show up better than a product that has 100x 5 star ratings and 2x 2 star ratings. Shouldn't the second product show up higher because it is statistically more trustworthy because of the larger number of ratings?

• Jquery and PHP rating function problem

  - by Sergio

  I know that I was already posted similar question but I just can't find the answer and figure it out how to solve this problem. I'm trying to customize Jquery Star Rating plugin (link text) but I do not know what to do to show the message based on response of PHP script. Jquery script successfully send rating data to PHP scripts that query the database and based on that echo message of proper or improper rating. What should I add to an existing JS code so I can get echo from PHP and base on that write a message on some DIV beside rating star? Jquery: $('#gal').rating('gl.php?gal_no=<?=$gal_no;?>&id=<?=$id;?>', {maxvalue:10,increment:.5, curvalue: <?=$cur;?>}); Simplified PHP code: $br=mysql_query("SELECT count(gal) as total FROM ...") if ... { echo '0'; } else echo '1'; } Jquery code successfully transmitted data to PHP script and when the PHP done with checking data echo the result ('1' or '0'). How can I get this PHP result back to Jquery and based on them write a message? Something like: if(data=="1") { $("#error").show("fast").html('not correct').css({'background-color':'#F5F5F5','border-color' : '#F69'}); }else{ $("#error").show("fast").html('correct').css({'background-color' : '#FFF','border-color' : '#3b5998'}); } If someone has an idea...I would appreciate it.

• DataBinding the AJAX Control Toolkit's Rating Control

  - by Nevada

  I'm attempting to use the AJAX Control Toolkit's Rating control in a DataBinding scenario. I have a ReuseRating column in my database that is a tinyint. It can hold values 1 through 5. Every record in the table has the value set to 1 currently. If I do this in my ItemTemplate everything works fine. I get 1 star filled in on my rating control. <act:Rating ID="ReuseRatingRating" runat="server" CurrentRating='<%# Convert.ToInt16(Eval("ReuseRating")) %>' MaxRating="5" StarCssClass="ratingStar" WaitingStarCssClass="savedRatingStar" FilledStarCssClass="filledRatingStar" EmptyStarCssClass="emptyRatingStar" /> Now I want to DataBind this in my EditTemplate like so. <act:Rating ID="ReuseRatingRating" runat="server" CurrentRating='<%# Convert.ToInt16(Bind("ReuseRating")) %>' MaxRating="5" StarCssClass="ratingStar" WaitingStarCssClass="savedRatingStar" FilledStarCssClass="filledRatingStar" EmptyStarCssClass="emptyRatingStar" /> Note, that I changed my Eval to a Bind in the CurrentRating property. This throws the following error. CS0103: The name 'Bind' does not exist in the current context Can anyone help me out on this one? I've been knocking my head against the wall for a couple of hours now.

• How to develop an english .com domain value rating algorithm?

  - by Tom

  I've been thinking about an algorithm that should rougly be able to guess the value of an english .com domain in most cases. For this to work I want to perform tests that consider the strengths and weaknesses of an english .com domain. A simple point based system is what I had in mind, where each domain property can be given a certain weight to factor it's importance in. I had these properties in mind: domain character length Eg. initially 20 points are added. If the domain has 4 or less characters, no points are substracted. For each extra character, one or more points are substracted on an exponential basis (the more characters, the higher the penalty). domain characters Eg. initially 20 points are added. If the domain is only alphabetic, no points are substracted. For each non-alhabetic character, X points are substracted (exponential increase again). domain name words Scans through a big offline english database, including non-formal speech, eg. words like "tweet" should be recognized. Question 1 : where can I get a modern list of english words for use in such application? Are these lists available for free? Are there lists like these with non-formal words? The more words are found per character, the more points are added. So, a domain with a lot of characters will still not get a lot of points. words hype-level I believe this is a tricky one, but this should be the cause to differentiate perfect but boring domains from perfect and interesting domains. For example, the following domain is probably not that valueable: www.peanutgalaxy.com The algorithm should identify that peanuts and galaxies are not very popular topics on the web. This is just an example. On the other side, a domain like www.shopdeals.com should ring a bell to the hype test, as shops and deals are quite popular on the web. My initial thought would be to see how often these keywords are references to on the web, preferably with some database. Question 2: is this logic flawed, or does this hype level test have merit? Question 3: are such "hype databases" available? Or is there anything else that could work offline? The problem with eg. a query to google is that it requires a lot of requests due to the many domains to be tested. domain name spelling mistakes Domains like "freemoneyz.com" etc. are generally (notice I am making a lot of assumptions in this post but that's necessary I believe) not valueable due to the spelling mistakes. Question 4: are there any offline APIs available to check for spelling mistakes, preferably in javascript or some database that I can use interact with myself. Or should a word list help here as well? use of consonants, vowels etc. A domain that is easy to pronounce (eg. Google) is usually much more valueable than one that is not (eg. Gkyld). Question 5: how does one test for such pronuncability? Do you check for consonants, vowels, etc.? What does a valueable domain have? Has there been any work in this field, where should I look? That is what I came up with, which leads me to my final two questions. Question 6: can you think of any more english .com domain strengths or weaknesses? Which? How would you implement these? Question 7: do you believe this idea has any merit or all, or am I too naive? Anything I should know, read or hear about? Suggestions/comments? Thanks!

• Moving media files while preserving itunes rating in itunes

  - by akurtser

  Hi, I've seen many threads on how to move an entire media collection from one machine to another. I want to organize my mp3 directories, but any copied file loses its reference from itunes library, thus, when I add it to itunes again, it'll have no rating data. I guess it's possible if I manipulate the itunes xml database, but I really don't want to mess with it "by hand".

• MySQL Rating system (calculating average from two tables).

  - by MussuR

  I have two tables, videos and videos_ratings. The videos table has an int videoid field (and many others but those fields are not important I think) and many records. The videos_ratings table has 3 int fields: videoid, rating, rated_by which has many records (multiple records for each fields from the videos table) but not for all records from the videos table. Currently I have the following mysql query: SELECT `videos`.*, avg(`videos_ratings`.`vote`) FROM `videos`, `videos_ratings` WHERE `videos_ratings`.`videoid` = `videos`.`videoid` GROUP BY `videos_ratings`.`videoid` ORDER BY RAND() LIMIT 0, 12 It selects all the records from table videos that have a rating in table video_ratings and calculates the average correctly. But what I need is to select all records from the videos table, no matter if there is a rating for that record or not. And if there aren't any records in the videos_ratings table for that particular videos record, the average function should show 0. Hope someone could understand what I want... :) Thanks!
