System EnvironmentFigure SEQ Figure \* ARABIC 1: RECIPE RECOMMENDATION SYSTEM, SYSTEM ENVIRONMENTThe recipe recommendation system of Turkish cuisine aimed at facilitating the selection of food which we are hard to decide. This system has two actor and one system (recommendation engine). As can be understood from the above, it is a system in which users play an active role. Admin and system have limited tasks.2.2. Functional Requirements SpecificationRecipe Recommendation System for Turkish Cuisine has 3 actors namely user, admin and recommendation engine.2.2.1. User Use CaseUse Case:Register UserLogin AccountSearch RecipeView RecipeView Recommended RecipeRate RecipeUpdate ProfileAdd Recipe to FavoriteView FavoritesDelete Recipe from FavoritesView ProfileAdd RecipeAdd new user to own accountAdd weekly meal planView past selected recipesChoose prospective recipesAdd own allergies and dietsDiagram:Figure SEQ Figure \* ARABIC 2: USER USE CASEBrief DescriptionIn general, user shall be able to register system, login to system, view his/her profile search recipes, add recipes and view recipes and view recommended recipes in the direction of the preferred recipes. All recipes have rate value and user shall be able to rate recipes. Every user have favorite recipes and user can add recipes to his/her favorites and view favorites. Moreover, users can add new user to their own account, so system recommends recipes based on this multiuser profile. Allergies and diet information, weekly meal plan can be added by user. Also, users can view past selected recipes and can choose prospective recipes and put them on their own calendar. In addition, if a recipe is not as preferred by the user as the former, user can delete this recipe from favorites.Initial Step-by-Step DescriptionIf User do not have account, user chooses Register button.The user registers and logs in to the system, system lists recommended recipes.The user enters recipe name into search box, system lists recipes and recommended recipes.The user selects recipe.The user rates recipes.The user adds own allergies and diets information.If the user wishes to add a new user to own account, press “Add new user” button in profile page.If the user adds the recipe to the favorite, the system lists his/her favorite recipes.If the user wishes to delete a recipe from favorite, press “Delete “Recipe” button in favorite part.If the user wants to add his/her special recipe to the system, press “Add Recipe” button, system lists textboxes for getting information about recipe. The user can view past selected recipes, by clicking “View past selections” button.The user can add new weekly meal plan by clicking “Make a meal plan” button. The user can choose prospective recipes and can put them on own calendar.If the user wants to update his/her profile, user press “Update Profile” button.The user presses “Save” button after updating profile and system shows his/her profile.2.2.2.

In addition, it shall be able to calculate average rate using the ratings given by users. Initial Step-by-Step DescriptionRecommendation engine shows recipes and recommended recipes, if any user search recipe.Recommendation engine shows recommended recipes in homepage after user logs in the system.Recommendation engine calculates average rate using user’s rates and number of users which give rate to recipe. 2.3. Actor CharacteristicsAll types of people can use this system. There is no any specification for them.All they need is the Internet connection to use this recommendation system.2.4. Non-Functional RequirementsIn this part, how this system works is shown. Some crucial non-functional requirements are accessibility, performance and security. First of all, accessibility is very important, so web page design should be done simply for users. In addition to that user should be reach easily what s/he is looking for. The other important thing is performance, searching for recipes and also recommendation to user should be done quickly, so speed is important. Finally, security is essential for users as important as in many systems, because users share their personal information.3. REQUIREMENT SPECIFICATIONIn this section, interface requirements, functional and non-functional requirements subtitles were described.3.1. Interface RequirementsIn user interface, according to historical and user information, some recipe recommendations will be shown to user. That is basically definition of the system. Moreover, five recommendations will be given to each user and one thousand recipes will be entered to system at the start. User interface phases are divided to three phases:UserIn this interface, users’ perspective is shown. Firstly, users can register and then login to the system. After that, they can search, view recipes and recommended five recipes, rate them. They can add recipe to favorites and to system, organize their favorite list and do some changes on their profile.Admin Admins are this system designers, at this point we are admins. We can search and view recipes, add new recipe to system or delete from the system, update them and lastly they can view users’ profile.Recommendation Engine Some algorithms will work in background of this system. This system will show recipes, recommended recipes to users and will calculate average of rate based on users’ rate. Users’ feedback as rating are very important to calculate them by the recommendation engine. 3.2. Functional RequirementsIn this section, main functions of recommendation system are clarified.3.2.1.
