OEP Risk Skoru Nedir? Ulke Guvenligini Nasil Olcuyoruz? What is the Risk Score? How We Measure Country Safety

Yurt disinda egitim planlarken en cok merak edilen sorulardan biri: "Bu ulke simdi guvenli mi?" Haberlerdeki basliklar, doviz kurundaki dalgalanmalar veya vize surecindeki belirsizlikler ogrencileri tedirgin edebilir. Meridian, bu soruya veri odakli bir yanit vermek icin OEP (Ogrenci Etki Puani) sistemini gelistirdi. One of the most common questions when planning to study abroad: "Is this country safe right now?" Headlines in the news, currency fluctuations, or visa process uncertainties can make students anxious. Meridian developed the Student Impact Score (OEP) system to provide a data-driven answer to this question.

OEP, bir ulkenin o anki kosullarinin uluslararasi ogrencileri nasil etkileyecegini 0 ile 100 arasinda bir puanla olcer. Yuksek skor = yuksek risk. Dusuk skor = ogrenci icin daha guvenli ortam. OEP measures how a country's current conditions might affect international students on a scale of 0 to 100. Higher score = higher risk. Lower score = safer environment for students.

1. Uc Alt Skor: Riski Nasil Hesapliyoruz? 1. Three Sub-Scores: How We Calculate Risk

OEP tek bir sayi degildir — uc bagimsiz veri kaynagindan turetilen alt skorlarin agirlikli ortalamsidir: OEP isn't a single number — it's a weighted average of sub-scores derived from three independent data sources:

Haber Analizi (%40 agirlik) News Analysis (40% weight)

Gemini Flash AI modeli, her ulke icin son 7 gunun haberlerini tarayarak ogrencileri dogrudan etkileyen olaylari kategorize eder: savas/kriz, siyasi istikrarsizlik, grev/protesto, dogal afet, ekonomik kriz. Her kategori farkli agirlikta skor uretir. Ornegin, aktif bir savas durumu tek basina skoru 40 puan artirabilir. The Gemini Flash AI model scans the past 7 days of news for each country, categorizing events that directly affect students: war/crisis, political instability, strike/protest, natural disaster, economic crisis. Each category generates a differently weighted score. For example, an active war situation alone can increase the score by 40 points.

Kur Riski (%35 agirlik) Currency Risk (35% weight)

Ogrencinin para birimine (TRY) karsi hedef ulke dovizinin son 90 gunluk degisimi analiz edilir. Kur %10'dan fazla deger kaybediyorsa yasam maliyeti planlamasi ciddi sekilde etkilenir. %30 ustu kayip ise kur riski skorunu maksimuma (100) cikartir. The 90-day exchange rate movement of the target country's currency against the student's currency (TRY) is analyzed. If the rate loses more than 10%, it significantly impacts cost-of-living planning. A loss above 30% pushes the currency risk score to maximum (100).

Vize Sureci (%25 agirlik) Visa Process (25% weight)

Ortalama vize bekleme suresi (gun cinsinden) ve surecteki belirsizlikler degerlendirilir. 30 gunun altinda = dusuk risk. 60 gunun uzerinde = yuksek risk. Vize sureci tamamen duran veya askiya alinan ulkelerde skor 100'e cikar. Average visa waiting time (in days) and process uncertainties are evaluated. Under 30 days = low risk. Over 60 days = high risk. Countries where visa processing is suspended score 100.

3. Neden Maksimum Guven Orani %92? 3. Why is Maximum Confidence 92%?

Meridian'da seffaflik en onemli degerlerimizden biridir. OEP sistemi hicbir zaman %100 kesinlik iddiasinda bulunmaz. Bunun bilinçli bir tasarim karari olmasinin nedenleri: Transparency is one of Meridian's core values. The OEP system never claims 100% certainty. This is a deliberate design decision for the following reasons:

• Haber analizi gecikmelidir: AI modeli son 7 gunun haberlerini analiz eder. Saatler icinde gelisen krizler (deprem, ani siyasi degisim) anliz penceresinin disinda kalabilir.News analysis has latency: The AI model analyzes the past 7 days of news. Rapidly developing crises (earthquakes, sudden political changes) may fall outside the analysis window.
• Kur verileri gecikmeli olabilir: Doviz kuru verileri gercek zamanli olmayip birkaç saatlik gecikme icerebilir.Currency data may be delayed: Exchange rate data may have a few hours of delay rather than being real-time.
• Vize surecleri surekli degisir: Bir ulkenin vize politikasi haftalik degisebilir. Veriler en son bilinen durumu yansitir, yarinin durumunu degil.Visa processes constantly change: A country's visa policy can change weekly. Data reflects the last known state, not tomorrow's situation.
• Etik sorumluluk: Ogrencilerin hayatlarini etkileyen kararlar icin %100 kesinlik iddiaisi etik degildir. "Bilmedigimizi biliyoruz" ilkesiyle hareket ediyoruz.Ethical responsibility: Claiming 100% certainty for decisions affecting students' lives is unethical. We operate on the principle of "we know what we don't know."

4. Gercek Dunya Ornegi: Almanya vs Ukrayna 4. Real-World Example: Germany vs Ukraine

Iki ulkenin OEP skorlarini karsilastiralim (ornektur, gercek zamanli veriler farklilik gosterebilir): Let's compare the OEP scores of two countries (illustrative; real-time data may differ):

Almanya orneginde: Haber skoru cok dusuk (aktif kriz yok), kur riski orta seviyede (EUR/TRY kuru dalgali ama stabil), vize sureci makul (~35 gun). Sonuc: ogrenciler icin guvenli bir destinasyon. Germany example: News score is very low (no active crisis), currency risk moderate (EUR/TRY rate fluctuates but stable), visa process reasonable (~35 days). Result: a safe destination for students.

Ukrayna orneginde: Haber skoru maksimum (aktif savas/kriz), kur riski yuksek (UAH ciddi deger kaybetti), vize sureci askida. Sonuc: ogrencilerin kesinlikle alternatif dusunmesi gereken bir ulke. Ukraine example: News score maximum (active war/crisis), currency risk high (UAH severely devalued), visa process suspended. Result: a country where students should definitely consider alternatives.

5. Veri Kaynaklari ve Teknoloji 5. Data Sources and Technology

Haber analizi icin Google Gemini 1.5 Flash modeli kullanilir. Bu model, hiz ve maliyet dengesi acisindan en uygun secimdir — gunluk yuzlerce haberi hizlica kategorize edebilir. ATLAS danismanin ile yaptigin sohbetlerde ise Claude modeli kullanilir cunku ogrenci sohbetlerinde dil kalitesi ve empati kritik onem tasir. For news analysis, the Google Gemini 1.5 Flash model is used. This model offers the optimal balance of speed and cost — it can quickly categorize hundreds of news articles daily. For conversations with your ATLAS advisor, the Claude model is used because language quality and empathy are critical in student conversations.

6. Nasil Guncelleniyor? 6. How is it Updated?

• Guncelleme sikligi: Her ulkenin OEP skoru saatlik olarak yeniden hesaplanir. Veri cache'i 1 saat gecerlidir; suresi dolan veriler yeniden cekilir.Update frequency: Each country's OEP score is recalculated hourly. Data cache is valid for 1 hour; expired data is re-fetched.
• Ani olay tetikleyicisi: Buyuk olayi haber kaynaklarinda tespit eden sistem, normal zamanlama disinda anliz guncelleme tetikleyebilir.Breaking event trigger: The system detecting a major event in news sources can trigger an analysis update outside the normal schedule.
• Trend gosterimi: Sadece anlik skor degil, son 7 ve 30 gunluk trend de gosterilir. Boylece "skor dusuyor mu yukseliyor mu?" sorusuna yanit alinir.Trend display: Not just the current score, but 7-day and 30-day trends are also shown. This answers the question "is the score trending down or up?"
• Seffaflik: Her OEP kartinda "Son guncelleme" zamani ve guven yuzdesi gosterilir. Kullanici verinin ne kadar guncel oldugunu her zaman bilir.Transparency: Every OEP card shows "Last updated" time and confidence percentage. Users always know how current the data is.
