A Web Based Rose Crop Expert Computer Science Essay

Published:

ABSTRACT

The Rose Expert System is basically gives the information regarding the diseases, viruses and their symptoms and chemical controls which are used to prevent the diseases and viruses of cultivation of Rose.

This Rose Expert Advisory System is simulation of more than one expert. This system is developed in Java Server Pages. There are two modules "Information system" and "Advisory system" are embedded in present system. For advising the farmers in the disease identification and preventive measures of Rose plantation, this "Rose Expert Advisory System" uses backward chaining mechanism for building Rule Based Expert system which results in giving exact disease. If rule base system fails in giving the exact disease then Rose Expert Advisory System provides an alternative system using Machine Learning Techniques - Optimization Algorithm, which produces subset of diseases with probabilistic values. Then the system uses Particle Swarm Optimization Algorithm for each disease by taking some sign values from the user and gives a nearest disease to the user with the preventive measures.

Expert system can be defined as a tool for information generation from knowledge. Information is either found in various forms or generated from data and/or knowledge. Text, images, video, audio are forms of media on which information can be found, and the role of information technology is to invent, and devise tools to store and retrieve this information. Statistical information is a good example of information generated from data while advises generated by an expert system is a good example of information generated from knowledge.

Roses are symbol of beauty, fragrance and are used to convey the message of love. In India roses are grown for cut flowers, making essential oil, rose water and gulkand. Dry petals of roses are also used for making incense sticks. Roses are native of Himalayas regions, Asia, China, Japan, Europe and North America. There are about 150 species but very few species have played a major role in evolving modern roses. These species are Rosa gallica, R. damascene

1.1 Rose Varieties

Red and dark red: Black Velvet, Crimson Glory, Happiness

Orange: Hawaii, Super, Star, Duke of Windsor

Yellow: Summer Sunshine, Golden Giant, Kiss of Fire, Double Delight

Pink: Eiffel Tower, First Love, First Prize

White: Virgo, White Christmas,

Bicolor: Suspense (red and yellow), Perfecta (pink and white),

Lavender: Blue, Africa Star, Paradise

Novel Color: Careless Love

1.2 Climate:

Rose can be grown successfully in variable climatic zones. However, moderate temperature, bright sunshine and high light intensity are good for flower production. It is suggested that the quality rose blooms are obtained during December to April, with approximately 5 to 6 blooms per plant each in 60 cm. and above, and 45 to 59 cm. category stem length. Roses do well in soils having pH upto 6.0 to 7.5 but it can also grow satisfactorily in alkaline soil with pH upto 8.4. Rose can be successfully cultivated in mild climate with good sunshine. It ceases to grow at vary low temperature

1.3 Temperature:

The growing temperature markedly influences the growth and flowering of rose plants. Seasonal variation in temperature has a pronounced effect on flowering, flower quality and longevity of field grown roses. A minimum temperature of 7.9 degree centigrade and maximum of 22.6 degree centigrade with 6 sunshine hours during winter season has been found to delay flower bud opening, improve flower quality and longevity in rose cultivar while 12.7 degree centigrade and, 27.8 degree centigrade minimum and maximum temperature respectively in spring season with 6 sunshine hours has been found to induce early flower bud opening and reduce the longevity of intact flowers considerably without affecting the quality of flowers as compared to winter seasons. The rise in temperature during summer and rain seasons adversely affects flower quality and longevity while inducing earliest flower bud opening.

1.4 Soil:

Rose plants grow well in good fertile soil. They can, however, be grown in all types of soil with proper drainage facilities. Well-drained medium loamy soil having adequate organic matter is ideal. The best soil reaction for roses should be in the pH range of 6.0 to 6.5. They will do reasonably well at a pH of 7.0 and slightly higher, but some nutritional problems may be encountered from time to time. A pH less than 6 is usually too low. A soil, which has been in cultivation and has a depth of at least 45 cm. is good for rose growing. The subsoil must have the capacity to retain sufficient moisture, bet at the same time permit good drainage. Adverse soil conditions, however, affect growth and flowering to a great extent. Budded pants have lesser tolerance to adverse conditions than unbudded rootstocks. Roses fall into the sensitive category of pants with respect to salinity and solidity tolerance.

1.5 Plantation:

Pick an area that has parlous of great flagging stain. Towering spot has a PH aligned station the amount of tart moment the blacken is at about 5. 5 - 7. 0.

Whole-length matter agnate manure or lime helps to aid the roots of your roses. You should soak the roots leverage drool or puddle clay for numerous memoir, and cut winterkill slab root ' s ends that are disastrous.

The basic 3 - 4 weeks succeeding planting your roses, you should imbue them generally. Generally this is when the top 2 inches of stain is dry. Roses requirement a lot of hydration and chop to stay on healthy.

2. PROPOSED SYSTEM:

The proposed system is Rose expert advisory system. It is divided into two aspects

Information System

Advisory System

In Information system, the user can get all the static information about different species, Diseases, Symptoms, chemical controls, Preventions, Pests, Virus of Rose flower and plants.

In Advisory System, the user is having an interaction with the expert system online; the user has to answer the questions asked by the Expert System. Depends on the response by the user the expert system decides the disease and displays its control measure of disease.

It is aimed at a collaborative venture with eminent Agriculture Scientist and Experts in the area of Rose Plantation with an excellent team of computer Engineers, programmers and designers.

This web application is expected to have the following features:

This web application provides time- to- time updates of Rose information to the users at their door steps regarding diseases, virus and its control measure which leads to good yields.

(Add facts to Working Memory or delete facts from Working Memory)

Until problem is solved or no condition match

The output of the this system produce the exact disease basing on the symptoms produced by the user which leads to a disadvantage that if any of the symptom does not match with the knowledge it will not produce any output for the further proceedings.

If the system1 (Rule Based System) unable to produce the exact disease then the system2 starts performing its work.

Optimization Algorithm: -

(SYSTEM-II)

Algorithm:

Optimization (Computation Vector, Memory Matrix, Resultant vector)

Computation Vector is the input vector that has to be mapped with the Memory Matrix and produce the result in the Resultant vector.

Computation Vector is an Input Boolean string of length n. and Memory Matrix is generated from the Knowledge base with all Boolean value of order m X n.

Step 1: Read the Computation vector as Boolean String of n length.

Step 2: Create a Resultant vector that initialize to null and counter to zero

Step 3: Construct the Memory Matrix of Boolean Value from the Knowledgebase.

Step 4: for i in 0 to m in the Memory Matrix of m X n

Make counter as zero. (Perform Step 4a and step 4b m times)

Step 4a: for j in 0 to n element in the row

Compare the jth element of the Computation vector with the jth element of the row

if both the element are equal

counter++ (increment the counter ).

Step 4b: Assign the ith element of the Resultant vector with the counter.

Step 5: (The resultant vector will be within the value of count which is has to be converted into

probability value of percentage value).

Step 6: For each element in the Resultant Vector replace the value by value/m*100 for Percentage

value of replace the value by value/m*1 by Probability value.

Step 7: End the process
